Hi,

you could try (ee inline comments):

chordTrack = \chordmode {
  \repeat unfold 2 {
    c1 d e f |
  }
}

%% make 'chordTrack' quotable
\addQuote "chrds" { \chordTrack }

notes = \relative c' {
  \repeat unfold 8 {
    c4 d e f |
  }
}

otherNotes = \relative c' {
  c1 d e f
  %% refer to the preexisting and named ChordNames-context, to put in the quotes
  \context ChordNames = "chrds-2"
    \quoteDuring "chrds" {
      %% while putting quotes into the relevant ChordNames-context, refer to
      %% the preexisting and named Staff-context to continue entering "normal"
      %% stuff
      \context Staff = "2" { g1 a }
    }
  b c
}

\score {
  <<
  \new ChordNames \chordTrack
  \new Staff \notes
  %% initiate a ChordNames-context which may be filled form 'otherNotes'
  \new ChordNames = "chrds-2"
  \new Staff = "2" \otherNotes
  >>
}

Not sure, if someone would call it "elegent" ...
